FIELD OF THE INVENTION
This invention generally relates to secure additive manufacturing, such as using 3D printers, and associated management networks.
BACKGROUND OF THE INVENTION
3D printing is an additive manufacturing process of making three dimensional solid objects from a digital file. One method for 3D printing is achieved by laying down successive layers of material until the three dimensional solid object is created. Each of these layers represents a thinly-sliced horizontal cross-section of the object. Other methods of 3D printing include selective laser sintering (SLS), selective laser melting (SLM), and stereolithography, among others. The 3D printing process begins by creating a virtual model of the object, typically a Computer Aided Design (CAD) file, and using specialized 3D printing software to âsliceâ the virtual model into hundreds or thousands of horizontal layers (depending on the desired fineness of the final printed object). The processed file with the sliced virtual model is then sent to a 3D printer that builds the model one layer at a time based on the individual slices of the virtual model.
Recent developments in 3D printing technology have reduced the cost and increased the availability of 3D printers and 3D printing software for the general public. However, such 3D printers and software generally remain limited to a single locally connected device for individual personal or professional use. There is, therefore, an unmet demand for a 3D printer management network that is secure, centrally managed, and accessible to individuals all around the world.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a 3D printer management network 100 , according to one embodiment of the invention. As shown in FIG. 1 , network 101 connects a plurality of user devices 102 , 104 , and 106 , a management server 120 , and a plurality of 3D printers
112 , 114 , and 116 . In one embodiment, the management server 120 may be run on one or more of the 3D printers
112 , 114 , or 116 within the 3D printer management network 100 . For illustrative purposes, FIG. 1 illustrates three 3D printers
112 , 114 , and 116 but many more could be implemented in the network 100 . The network 101 may be any known communications network, including the Internet, a Local Area Network (LAN), a Wide Area Network (WAN), etc. User devices 102 , 104 , and 106 may comprise any suitable device for transmitting a request for 3D printing over the network 100 . For example, user devices 102 , 104 , and 106 may comprise personal computers (PCs), laptops, smartphones, tablets, and the like. Management server 120 may also comprise any suitable device for managing the plurality of 3D printers
112 , 114 , and 116 over the network 101 , including a PC, a laptop, a rackmount system mounted in a server cage, etc.
Because network 101 connects the plurality of user devices 102 , 104 , and 106 , the management server 120 , and the plurality of 3D printers
112 , 114 , and 116 , the devices comprising the secure 3D printer network 100 may be distributed geographically as necessary. For example, in one embodiment, 3D printers
112 , 114 , and 116 may be located remotely from the management server 120 , which in turn, is located remotely from the user devices 102 , 104 , and 106 . Given the distributed nature of the 3D printer management network 100 , in one embodiment, the communications between the plurality of user devices 102 , 104 , and 106 , the plurality of 3D printers
112 , 114 , and 116 , and the management server 120 over the network 101 are secured using any suitable technique. In various embodiments, the communications may be secured using public key cryptography such as RSA, Transport Layer Security (TLS), Secure Sockets Layer (SSL), or any combination or variant thereof.
While FIG. 1 shows three user devices 102 , 104 , and 106 , and three 3D printers
112 , 114 , and 116 , it should be understood that the 3D printer management network 100 is not limited to any specific number of user devices and 3D printers, and is scalable from a single user device and a single 3D printer, to hundreds or thousands, or more, of such devices. Additionally, central server 120 may comprise a single device, or in other embodiments, may comprise multiple devices centrally managing the plurality of 3D printers
112 , 114 , and 116 .
FIG. 2 shows a block diagram of the structure of the management server 120 of the 3D printer management network 100 shown in FIG. 1 , according to one embodiment of the invention. As shown in FIG. 2 , the management server 120 comprises a processor 202 in communication with DRAM 204 , persistent storage 206 , peripheral interface 208 , and network interface 210 . In another embodiment, the persistent storage 206 need not be persistent, and may comprise volatile memory devices, or a combination of volatile and non-volatile memory devices. In yet a further embodiment, the persistent storage 206 and the DRAM 204 may be the same device.
Network interface 210 connects the management server 120 to the network 101 . Peripheral interface 208 connects the management server 120 to peripheral input devices 201 . Peripheral interface devices 201 may include a keyboard, a mouse, a touch panel, or any other suitable device to input user commands and control the management server 120 . Alternatively, in one embodiment, control of the management server 120 is performed remotely over the network 101 through the network interface 210 . Persistent storage 206 stores user account subsystem 212 , security subsystem
214 , and 3D printer management subsystem 216 .
User account subsystem 212 stores individual user account information, including the user's 3D printing history, stored 3D printing files, available funds, and any pending 3D printing requests. In one embodiment, the individual user account information is stored remotely and the user account subsystem 212 is configured to access the remotely stored information by causing the processor 202 to retrieve the information through the network 101 via the network interface 210 . In this embodiment, the individual user information may be stored in the cloud, in a network-attached storage (NAS) device, or any other suitable remote storage device. For enhanced security, in one embodiment, the individual user information is encrypted using any suitable method.
Security subsystem 214 stores user authentication information with respect to each individual's user information stored by the user account subsystem 212 . The user authentication information may comprises a user's username and associated password, a user's identification and associated pin number, a user's card number, a user's RFID tag, a user's biometric data (such as a fingerprint image), or any other suitable identification information, or combination thereof, to verify the user is properly authorized to access the user information stored or accessible by the user account subsystem 212 . In one embodiment, the user authentication information is stored remotely from the management server 120 , and the security subsystem 214 is configured to access the remotely stored authentication information by causing the processor 202 to retrieve the information through the network 101 via the network interface 210 . In this embodiment, the user authentication information may be stored in any suitable remote storage device. In one embodiment, the user authentication information is encrypted using any suitable method.
Additionally, security subsystem 214 stores administrator authentication information. Once authenticated, the security subsystem 214 is configured to allow the administrator to access all of the individual user account information stored or accessible by the user account subsystem 212 . Once given access to the individual user account information, an administrator may view or modify the user account information. Additionally, in one embodiment, the security subsystem 214 is configured to allow the administrator to lock or unlock a user's account. For example, if a user has violated a rule or regulation imposed by an administrator, the administrator may lock the user's account to prevent the user from accessing the secure 3D printer network 100 .
3D printer management subsystem 216 is configured to retrieve and make available real-time information regarding the status of the 3D printers
112 , 114 , and 116 of the secure 3D printer network 100 (shown in FIG. 1 ) to both the authorized users and the administrators. In one embodiment, the 3D printer management subsystem 216 is configured to either periodically or asynchronously fetch the status of each individual 3D printer
112 , 114 , and 116 to determine if a respective 3D printer
112 , 114 , and 116 is idle (available to receive and print a 3D printing file), is in progress (in the process of printing the 3D printing file), is completed (printing has been completed but the user has not retrieved the printed object), has encountered an error, or requires maintenance, among other statuses that may also be applicable to each of the 3D printers
112 , 114 , and 116 .
Additional status information, such as the amount of printer material remaining (e.g., length of filament string), the estimated time remaining for the 3D printing to be completed, printer operation time (indicating total for the 3D printing to complete), total occupation time including print time and the amount of time the 3D printing has been finished (indicating the amount of time the object has been waiting to be picked up by the user), and the estimated amount of time before a user picks up the 3D printed object (can be an estimate based on the average pickup time, or an estimated pick up time provided by the user, for example) may also be provided to users and administrators.
In another embodiment, the plurality of 3D printers
112 , 114 , and 116 periodically transmit their current status over the network 101 to the management server 120 , and the 3D printer management subsystem 216 is configured to cause the processor 202 to retrieve that information via the network interface 210 for use by the 3D printer management subsystem 216 . In one embodiment, the real-time information regarding the status of the 3D printers
112 , 114 , and 116 of the secure 3D printer network 100 is stored in the DRAM 204 .
In one embodiment, the management server 120 is configured to receive a 3D printing request to print a 3D printing file from a user device 102 , 104 , or 106 , and associates the 3D printing request and 3D printing file with the user's account. After the 3D printing request and 3D printing file is received by the management server 120 , the user may then access the 3D printing file from one of the 3D printers
112 , 114 , and 116 for printing by logging into their account and retrieving the 3D printing file from the management server 120 .
In another embodiment, 3D printing files containing metadata for the 3D print job (i.e., the details of the print job, including the print job file name, the estimated amount of time to print, material consumption, owner of the print job, and a unique identifier that allows the management server 120 to associate user account information with a specific 3D print job) may be stored on and retrieved from any portable storage device connected to one of the 3D printers
112 , 114 , and 116 . In this embodiment, the 3D printers 112 , 114 and 16 are configured to retrieve and store the metadata for the 3D print job in a non-volatile memory (not shown) along with user account information and any status updates related to the print job. The 3D printers
112 , 114 and 116 send the metadata for the 3D print job to the management server 120 when communication can be established with the management server 120 over network 101 . Alternatively, the metadata may be separately transmitted to the management server 120 from a user device 102 , 104 , or 106 when communication can be established with the management server 120 over network 101 .
In yet a further embodiment, 3D printing files may be generated by additional devices, such as 3D scanners or X-ray imagers, and the files may be transmitted to the management server 120 , transmitted to a user device 102 , 104 , or 106 , or retrieved using a portable storage device for 3D printing. Depending on the method of transmission and/or retrieval of the 3D printing files generated in this manner, either of the embodiments described above may be utilized to initiate a 3D printing request for the 3D printing file.
In another embodiment, the management server 120 is configured to receive a 3D printing request from a user device 102 , 104 , or 106 of an authorized user over the network 101 , and directly transmit the 3D printing file specified by the user to a selected 3D printer
112 , 114 , and 116 of the secure 3D printer network 100 . In one embodiment, the user may view the status of the 3D printers
112 , 114 , and 116 , and select one or more of the 3D printers
112 , 114 , and 116 to print the 3D printing file. In another embodiment, the user may specify how many copies of the 3D printing file the user wants to print, and the management server 120 dynamically selects the 3D printers
112 , 114 , and 116 to transmit the 3D printing file to for printing. In this embodiment, the management server 120 may dynamically select the 3D printers
112 , 114 , and 116 based upon the real-time information regarding the status of each of the 3D printers
112 , 114 , and 116 .
In one embodiment, the management server 120 is configured to allow an administrator to remotely take control of any 3D printer
112 , 114 , and 116 of the secure 3D printer network 100 . An administrator may cancel any pending print job, whether in progress or awaiting printing, re-arrange pending print jobs, power up, shut down, or restart the 3D printers
112 , 114 , and 116 , and lock or unlock 3D printers 112 , 114 , and 116 (discussed in further detail below in connection with FIG. 3 ).
FIG. 3 is a block diagram of the structure of a 3D printer 112 of the 3D printer management network 100 of FIG. 1 , according to one embodiment of the invention. As shown in FIG. 3 , the 3D printer 112 comprises a processor 302 in communication with a secure memory 304 , user interface 308 , 3D printing area 306 , and network interface 310 . Network interface 310 connects the 3D printer 112 to the network 101 . 3D printing files that are received over the network 101 via the network interface 310 are stored in the secure memory 304 . Secure memory 304 may either be persistent or non-persistent memory, or both. Because the 3D printer 112 must be publicly accessible, secure memory 304 may be electronically or physically secured, or both, to protect the integrity and security of the user's 3D printing files. Electronic security for the secure memory 304 may comprise any suitable encryption techniques. Physical security for the secure memory 304 may comprise locking the secure memory 304 in a secure location within the 3D printer 112 .
